Sulfonic acid functionalized ionic liquids for dissolution of metal oxides and solvent extraction of metal ions.
New sulfonic acid functionalized ionic liquids (SAFILs) with bis(trifluoromethylsulfonyl)imide anions were synthesized. These ionic liquids are strong Brønsted acids and can solubilize metal oxides. Water-immiscible SAFILs were used as organic phases in solvent extraction studies.
متن کاملEfficient enrichment of glycopeptides with sulfonic acid-functionalized mesoporous silica.
This work presents an efficient and selective enrichment method for glycoprotein/glycopeptides with sulfonic acid-functionalized mesoporous silica (SBA-15-SO3H), which is synthesized via simple oxidation of -SH groups with H2O2. The functionalized SBA-15 shows large surface area and accessible pores, and can selectively adsorb glycopeptides via hydrogen bond and hydrophilic interaction. Upon th...
متن کاملCatalytic reactions in ionic liquids.
The chemical industry is under considerable pressure to replace many of the volatile organic compounds (VOCs) that are currently used as solvents in organic synthesis. The toxic and/or hazardous properties of many solvents, notably chlorinated hydrocarbons, combined with serious environmental issues, such as atmospheric emissions and contamination of aqueous effluents is making their use prohib...
متن کاملBis-sulfonic acid ionic liquids for the conversion of fructose to 5-hydroxymethyl-2-furfural.
Homogenous bis-sulfonic acid ionic liquids (1 mol equiv.) in DMSO (10 mol equiv.) at 100 °C efficiently mediated the conversion of D-fructose into 5-hydroxymethyl-2-furfural in 75% isolated yield, which was roughly a 10% increment compared to the case of the mono-sulfonic acid ionic liquids.
متن کاملSulfonic Acid Group Functionalized Ionic Liquid Catalyzed Hydrolysis of Cellulose in Water: Structure Activity Relationships
Catalytic activities of eight sulfonic acid group functionalized ionic liquids in water were compared for the hydrolysis of Sigmacell cellulose (DP ~ 450) in the 150-180°C temperature range by measuring total reducing sugar (TRS) and glucose produced. The catalytic activity of acidic ionic liquids with different cation types decreases in the order imidazolium > pyridinium > triethanol ammonium ...
